Steps to Reproduce

I installed Sentry on Kubernetes 1.31 using Helm chart sentry:29.4.0.
I configured email delivery via SMTP without authentication.
The SMTP test from https://sentry.test.eu/manage/status/mail/ works correctly.

However, from my account settings page:
https://sentry.test.eu/settings/account/emails/
when I click Resend verification, the email is not delivered.

Where can I check:

• the queue state,
• worker processing,
• or any related errors for this email task?

It looks like the message is being queued but not processed.

Expected Result

Fix or any help

Actual Result

From the logs, I can see that the task is sent to the queue, but the email is never actually sent.

The email sending log should exists on the default taskworker pod. Can you check there and can you find anything related to SMTP?

i checked, its all log in a sentry-taskworker-default-7c84fbcd99-976mn pod

Do you mind opening a new issue over at sentry-kubernetes/chart repository? I think this is a configuration issue. On the default Docker Compose setup, we can receive emails just fine.
